The ancient art of enameling, noted for its brilliant, glossy surface, which is hard and long-lasting has been esteemed for thousands of years. Each handcrafted charm is hand-painted with various layers and shades of powdered, colored glass, then fired at high temperatures. The powder melts, flows, and then hardens to a smooth, durable vitreous coating that is fused to the precious metal. Charms vary slightly in color, making each one unique.
